## What it is
APScheduler (Advanced Python Scheduler) is a Python library for scheduling tasks with cron-style, interval, calendar-based, and one-off triggers, doubling as a job queue. It supports persistent job stores (PostgreSQL, MySQL, SQLite, MongoDB), event brokers for multi-node deployments, and both synchronous and asyncio/Trio flavors.

## Use cases
- run a python function every day at 9am
- schedule cron jobs inside a python application
- queue background tasks in asyncio app
- persist scheduled jobs across restarts
- distribute scheduled tasks across multiple workers
- replace crontab with in-process scheduling

## When to choose
- you need in-process task scheduling in Python with cron-like triggers
- you want persistent, shared job stores for high availability
- you need both sync and async (asyncio/Trio) support
- you want a lightweight alternative to external schedulers like Celery beat

## When to avoid
- you need a full distributed task queue with retries and complex routing (consider Celery)
- you want to schedule jobs across non-Python systems
- you plan to use the v4.0 pre-release in production, as it may change incompatibly

## Facets
- artifact type: library
- maturity: active
- function: scheduling, workflow-automation, concurrency
- domain: developer-tools, backend
- platform: python, cross-platform
- tags: cron, task-queue, asyncio, job-scheduler, trio, automation
